  1. What is the major role of glycolysis?

 to produce energy (2  ATP) both aerobically and anaerobically

100

NAme that GSD 

Glucose-6-phosphatase deficiency in chromosome 17.

Affects liver, kidney and intestine;

Severe fasting hypoglycemia

Von Gierke’s disease (Type-1a)

100

During Digestion we convert ( Fillin the blanks)

Convert _______ to ________

Convert polymers to monomers

100

Fill in the Blank

______ nitrogen balance occurs when the protein breakdown exceeds the use of protein for building molecules eg. infection, injury, burns, depression, starvation.

Negative nitrogen balance occurs when the protein breakdown exceeds the use of protein for building molecules eg. infection, injury, burns, depression, starvation.

Why is LDL more dangerous for the human body?

High plasma cholesterol levels correlate to more  atherosclerosis (clogging of arteries) and more deaths

200

What is the storage form of glucose ?

Glycogen

200

Name that GSD 

Lysosomal α-glucosidase deficiency

Excessive glycogen in the lysosomes

General (heart, liver, muscle)

Cardiomegaly, early death

Enzyme replacement therapy available

Pompe’s disease (Type-II)

         (the only lysosomal GSD)

200

This begins the breakdown process in the mouth?

Salivary amylase begins the breakdown process in the mouth

200

True or False

Complete proteins are found in eggs, milk, meat, fish.

Incomplete proteins are found in legumes (soybeans, kidney beans, lentils), nuts and seeds, grains cereals and vegetables.


TRUE 

Complete proteins are found in eggs, milk, meat, fish.

Incomplete proteins are found in legumes (soybeans, kidney beans, lentils), nuts and seeds, grains cereals and vegetables.

200

What are essential fatty acids?

Essential fatty acids are cis-polyunsaturated fatty acids.

Our cells cannot make them. We need essential fatty acids to make local hormones like, prostaglandins, leukotrienes, etc. Vegetable oils, fish oil are rich in polyunsaturated fatty acids.

300

True or False 

Nucleic acids & Cholesterol are energy sources.

Nucleic acids & Cholesterol are NOT energy sources

300

Name that GSD 

glycogen phosphorylase (Skeletal muscle Myophosphorylase) deficiency

Block muscle glycogenolysis

Skeletal muscle affected

McArdle’s syndrome (Type-V)

300

What stops salivary amylases and causes stomach acid to kill bacteria ?

Low pH stops salivary amylases and causes stomach acid to kill bacteria

300

Ammonia is formed ?

from amino acids, glutamine, bacterial action in the intestine, amines, purines and pyrimidines.

300

One of these is NOT true of fatty acid-based lipids.

One of the incorrect options: 

1. Source of energy (Best source)

2. Structural (part of cell membrane)

3. Insulator (sphingomyelin)

4. Cell Signaling (diacylglycerol or DAG)

5. Local hormones (prostaglandins, leukotrienes)

6. Reduce surface tension (lung surfactant)

Used in lungs to increase not reduce surface tension

400

Why can’t humans use cellulose as a source of energy?

Our digestive juices lack enzymes that can hydrolyze the β-glycosidic linkages found in cellulose, so although we can eat potatoes, we cannot eat grass.

400

Name that GSD

TReatment for this didease 

Treatment: nocturnal gastric infusion of glucose or regular administration of uncooked cornstarch

Von Gierke’s disease (Type-1a)

400

True or False 

Pancreatic α-Amylase breaks only down 

Maltose, Lactose, Fructose

False

IsoMaltose, Maltose, Lactose, Sucrose



400

This disorder leads to tremors, slurring of speech, and blurring of vision?

Hyperammonemia (elevated levels of ammonia) leads to tremors, slurring of speech, and blurring of vision.

400
3 Main reasons why Cholesterol is important ?

Importance of cholesterol: component of cell membranes; starting material for making bile acids, steroid hormones.

500

Rate-limiting enzyme in glycogenolysis, it generates 

Generate glucose-1-phosphate from the terminal alpha-1,4-glycosidic bond

Glycogen phosphorylase

500

Name that GSD 

Temporary weakness and cramping

No lactate increase after exercise

Relatively benign and chronic

McArdle’s syndrome (Type-V)

500

True or False

True

Monosaccharaides  (Glucose, galactose, fructose etc) are absorbed to the blood stream(insulin is not needed for absorption of glucose from small intestine)

500

Fill in the blank

Amino group (NH2) from most amino acid is  removed  via _________

Amino group (NH2) from most amino acid is  removed  via transamination

500
